For this assignment, you are to describe the processes of evolution in essay format. In order to properly execute this assignment you are going to need to cover a number of concepts. In general you should describe each of the Four Forces of Evolution, to a degree that lets me know that you understand each of them. You should also cover both the concept of species and population. Given that variation is also critical to the process, a description of variation between populations is also necessary. Finally, Isolation Mechanisms and the Speciation event itself must be covered. All of the concepts are interrelated and your essay must reflect that. Be careful as this is easily the most difficult assignment you will have to complete for this class.
